Not so much an AIBU but just need to vent. I was sitting in my usual coffee shop and after half an hour had to move because of a girl on the next table's screeching laugh shattering my eardrums every 30 seconds. It wasn't just occasionally,it was every other thing she or her 2 companions said had to be accompanied by a high pitched screech of laughter. So I moved a comfortable distance away,only to have the woman on the next table start watching a TV programme on her tablet,with the volume up really loud. Haven't these people ever heard of earphones?! Am I just getting grouchy as I get older or do some people have absolutely no consideration of how their noise impacts on other people?
